Filed: 1990-02-28
Abstract: PURPOSE:To allow the stable execution of high-density recording with the floating type thin-film assembly by specifying the spacing from the end on the air outflow end side of a slider to a magnetic gap. CONSTITUTION:The floating type thin-film magnetic head assembly 11 is the ring type magnetic head formed with a thin film of a magnetic converting part (transducer) 13 of a perpendicular direction on the air outflow end side 12a of the slider 12. This head is so constituted as to satisfy relation I when the spacing between the working part (magnetic gap) 13c of this transducer 13 and the end 14a on the air outflow end side of an air bearing surface 12A is designated as l(mum), the attack angle of the slider at the time of stable traveling as theta(murad) and the shortest recording wavelength to be used of the information signal to be magnetically recorded and reproduced as lambdamin(mum). The spacing loss at the shortest recording wavelength lambdamin to be used is then kept within 0.5dB which is a general permissible value. The stable high-density magnetic recording is thus executed.

Title: Semiconductor device
Inventor: OGASAWARA KAZUO
IPC: H01L27/01
Filed: 1982-03-25
Abstract: PURPOSE:To obtain a resistance circuit network which has high integration and high accuracy by alternately arranging the first and second polysilicon resistors insulated from each other on an insulating film of an Si substrate and connecting the resistors equally in number. CONSTITUTION:The first polysilicon unit resistors 5 are formed by a photoetching method on an oxidized film 8 on an Si substrate 10, an oxidized film 9 is covered, and the second polysilicon unit resistors 6 are similarly formed. Accordingly, the resistors of approx. double in number can be formed on the same area. Windows 7 are opened, and lead conductors 1-3 and mutually connecting conductors 4 are then formed. Since the unit resistors are equal in number even if the variation in the resistor is independently produced due to different impurity diffusion amounts of the first and second polysilicons, the ratio of the resistance values can be maintained constantly. The time constant of the CR is controlled by the diffusion of the impurity, thereby forming a CR filter having high integration and high accuracy.

Abstract: PROBLEM TO BE SOLVED: To obtain a stage movement apparatus by which a stage is moved to a desired position irrespective of the mounting system of a moving mirror by a method wherein the stage is moved to a direction in which coordinates converted into an apparatus coordinate system agree with interference-measured coordinates. SOLUTION: A measuring part 15 measures a component ΔY which is parallel to a Y- coordinate axis, in an apparatus coordinate system, which forms a coordinate axis in the normal-line direction of two mirror surfaces of a moving mirror 14 regarding the vector 11 of a sample 12. On the basis of the component ΔY, on the basis of the angle θs of inclination of the vector 11 to an x-coordinate axis in an orthogonal coordinate system and on the basis of a length L, an angle computing part 16 finds a angle θy formed by a y-coordinate axis in the orthogonal coordinate system with reference to the Y-coordinate axis. On the basis of the angle θy or the like, an angle computing part 16 finds an angle θx formed by the x-coordinate axis with reference to an X-coordinate axis.  An interference measuring part 18 obtains position coordinates in the apparatus coordinate system of a stage 13 which supports the sample 12 by means of an interference measurement with reference to a mirror surface 14. Then, on the basis of the deviation of the angles θy , θx , a stage movement mechanism 19 converts coordinates in an orthogonal coordinate system into coordinates in the apparatus coordinate system, and the stage 13 is moved to a direction in which the coordinates agree with the interference-measured coordinates.

Abstract: PROBLEM TO BE SOLVED: To remove surface roughness from a high temperature superconductive(HTS) film by exposing a high temperature superconductive thin film at a specified angle to a surface of a thin film by inert ion beam. SOLUTION: A protection layer 15 of an organic polymer PMMA film is fixed to an HTS film 14 attached to a proper substrate 13.

In any case, it is necessary to make energy of beam higher than at least a cohesion energy density of surface roughness to be removed during milling. As a result, microwave surface impedance MSI of the film 14 can be improved on receiving such a treatment.

Abstract: PURPOSE:To surely perform data transfer even when contention occurs in addresses by sending a standby signal to a processor having a standby function and making the processor make access to a shared memory preferentially while a fast processor without having the standby function makes access to the shared memory. CONSTITUTION:A digital signal processor(DSP) 1j is provided with a fast processing function compared with a universal processor.
